While doing research on Lithuanian culture for Love Songs of the Revolution, I came upon a YouTube video that changed everything for me. Fuzzy images from a massive demonstration in 1989 are overlaid with a rock anthem whose words I couldn't understand, but whose meaning couldn't be more clear.

I started digging in earnest, reading everything I could find online and in print about the Baltic Way, a human chain that ran from Vilnius, the capital of Lithuania, to Rīga in Latvia, all the way to Tallinn, Estonia on the Gulf of Finland. People held hands across more than 370 miles to demand independence from the Soviet Union. The date was August 23, and it was the 50th anniversary of the 1939 Molotov-Ribbentrop Pact, the treaty where the Nazis and Soviets quietly divided up Eastern Europe between themselves and agreed not to fight each other. It didn't last, and yet had far-reaching consequences.

Imagine: this was organized before the internet

The Baltic Way was a major milestone in the Singing Revolution that swept the three Baltic nations in the late 1980s and ultimately led to their independence. No one knows exactly how many people showed up in the streets that day, but estimates run between one and two million people across the three countries.

This year marks the 25th anniversary of the Baltic Way. It's an amazing story and a historic moment in European history. We in the West know about the fall of the Berlin Wall and the demonstrations in Tiananmen Square in China, both of which happened the same year, but have never heard about the Baltic Way. Once I learned about it, I knew it would have an important place in my novel. There on he streets of Vilnius in 1989, the crowds holding hands around them and singing for their freedom, the lives of Martynas and Indre are irrevocably changed.
